La voie de 60 sur les Fronts Francais de la Guerre de 14 - 18. (Crochat Locomotive - Gas / Elecrtic)

"Cat Food Can Locomotive"

This was first posted to the On30 Yahoo Group, message number 17078 on 25 Dec 2007. The photos are located in this Photo Album on that site:


Hi All,

Having been inspired by the likes of GW, Jeff, Ted,
Martin and others I decided to add a few of the tips
and tricks I have learned since returning to model
trains this past May.

Looking over my inventory of skills I seem to have
quite a few:

I don't photo etch but I do really well with the etch
a sketch.

I don't solder but I do glue with the best of them.

I don't photoshop but I do shop ebay a lot.

I don't type well but I do hit the copy machine button
almost always in the correct spot.

I don't have children but I do have a bunch of cats.
They eat mostly dry food but they do get a few
(aluminum) cans of Friskies each day as a treat for
not forgetting where the kitty liter box is located.

So, armed with all these skills, I embarked upon my
first scratch built Locomotive project this past week.

If you read the subject line of this email you have a
clue as to what is coming next.

Sometime back in October of this year [2007] someone on a
yahoo train group posted some information on a new
book by a French author and model train builder named
Christian Cenac.  He had written 4 other books about
the French WW I trains that supported the trench style
of warfare.  One of those books was said to be full of
scale drawings.  I have always been interested in the
"Trench Style of Warfare from WW I"

The books didn't seem to be sold here in the US so I
checked my "library books listing" and found one of
the 4 titles.  Two copies of one of his books were
listed and were in libraries here in the US.  I asked
my library if they would try an Interlibrary Loan for
that title.  The request went out to the two libraries
on 31 Oct 2007.  A few weeks ago I got a notice that
the request had been denied.  I assumed that it was
from both libraries.  Then this past Monday I got
another notice about a different book I had on request
that did come in and that I could come and pick it
up.  When I got there they had two books.  One was the
French book and had come from "The Library of
Congress".  The book has 48 foldout pages of plans in
1/35" scale, many pictures and lots of text - in
French.   One of the locomotives was this thing called
the Crochat Locomotive.  It is a gas / electric
locomotive and was built to move train cars on the 60
mm gauge rail lines in support of the WW I trench
fighting for the French. 


I worked on the drawings and changed the scale from
1/35" to 1/48" (On30). It looked like it might be an easy
project. I made the first one out of card stock. I
love those big copy machines.





I have been slowly working on another project, a BVM
conversion, and had a Bachmann HO - GE 44 Ton ready to
use as the donor motor / chassis. I sat the mock-up
on the 44 ton chassis and had a look. Looked close
enough for me.



As I said above that I have a number of pet cats and they generate a few empty aluminum food cans each day. I have used these aluminum cat food cans for other non-train projects in the past and thought I would try using them for this Locomotive.

This is also my first scratch built Locomotive.

As I also said I don't solder so I glued the aluminum
panels over the card stock model.



This seems to have worked OK.



As I continued to work on the Crochat Locomotive I
gave it a coat of primer and started working on the
frame. I have added the first coat of black paint and
continued to work on the frame and have the started on
the side rails.




Card Stock Side Frames.











The card stock / cat food aluminum can material worked
well enough that I am sure I will be using this method
for several more projects. Laminating the thin
aluminum to the card stock makes for a reasonably
strong body for "The Crochat Locomotive".

Hi, Bill. That's a really great way to upcycle, as the artists say, and it turned into a very sharp looking model. I love interlibrary loan, by the way. I've gotten railroading books that way before.
